No no no... you are confusing direct (e.g. income and capital) taxes and indirect (e.g. value added and sales) taxes. VAT is never paid twice, it is either paid in the country of origin or country of destination, but never in both countries. Inside EU VAT area when selling to a private person, VAT is paid in the country of origin (in Jolla's case Finland), and when selling to outside of EU VAT area, it is paid in the country of destination.
